Latest Patents
Huggins holds a patent for an innovative method of embedded signalling. This patent describes a code signal that represents a sequence of code symbols carrying digital information. The frequency components of the code signal are confined to a preselected signalling band within the bandwidth of an audio signal. The audio signal is continuously frequency analyzed, allowing the code signal to be dynamically filtered. This results in a modified code signal that can be combined with the audio signal to create a composite audio signal, which remains indistinguishable from the original audio signal by listening. The digital information can be recovered from this composite audio signal through a complementary procedure.
